From bottom to top: Pelikano 'Deep Space', Future, Level 1 (Level 65), GO (M75)
All of these pens have been individually reviewed elsewhere in FPN reviews, so this review is more a summary of their similarities and differences. Most importantly, they all have the same steel nib (in fact, all the pens here have an 'M' nib) and section. However, the tip of the Pelikano is larger than on the others, probably in order to allow novice users to write smoothly from a wider range of angles, and perhaps as a consequence, it writes wider than the others. The nibs on the Future and Level 1 are identical, while that on the GO is also the same, but gold-plated and has a couple of curves and the Pelikan logo in place of the plain 'M' on the other three.
These pens cover the gamut of 'student'-level offerings from Pelikan. Each one offers (or at least emphasizes) a different way of filling.
The Pelikano is best used with cartridges only. In fact, as a post from Dillo says, the point of the Pelikano's feed that enters the cartridge is narrower than the usual, so that a cartridge used on another Pelikan will come loose when you attempt to fit it to the Pelikano (I have verified this with a cartridge from my Ductus). Similarly, if you insert a converter into a Pelikano, you should keep it there and not try re-inserting it into the Pelikano if you have previously used it on any other Pelikan. The section comes with an excellent textured grip with indentations for the user's fingers (I believe the indentations come in 'right-hander' and 'left-hander' versions).
The Future takes cartridges and converters, and mine came with a converter (in fact, the holes in the barrel are best suited for viewing ink level in a converter).
The Level 1 uses a unique filling mechanism with a needle being injected from a special ink bottle (sold with the pen, or separately) into the bottom of the barrel, such that when the (plastic) bottle is squeezed, the ink squirts out through the needle into the barrel. You may consider this simply a fancier method of ED filling, but the trick here is that the first reservoir into which the ink goes is merely the reserve tank. You then turn the valve at the bottom of the pen's barrel to draw some of this ink into a smaller main tank. Since the reserve tank's capacity is several times that of the main tank's, it is easy to keep the main tank full before undertaking a flight, say, so as to minimize the risk of leakage during the flight. Unfortunately, the Level 1 has been discontinued, though the ink bottles are still sold.
The GO is a piston-filler, which is probably why it merits the prestigious M-numbering of the Souveran series. Otherwise, it has nothing in common with even the lowliest Souveran, the M150. Of the four pens pictured here, the GO puts down the wettest line. Alas, the GO has also been discontinued.
Whichever one you use, be assured that the nib is buttery smooth! They are all excellent writers, but I especially love the Level, as it's a little larger than the others and feels better balanced. However, the Pelikano 'Deep Space' looks very distinguished and is probably the best-looking of the lot. As I said above, the Level 1 and GO have been discontinued, so your only choices for an in-production student pen from Pelikan are the Pelikano Jr., Pelikano, and Future.
